DRV8825 Stepper Motor Driver
MAXIMUM CURRENT =2.2AMP.
This breakout board for TI?s DRV8825 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2?V to 45?V and can deliver up to approximately 1.5?A per phase without a heat sink or forced air flow (rated for up to 2.2?A per coil with sufficient additional cooling). The driver has a pinout and interface that are nearly identical to those of our?A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.
